An alternative for moduli stabilisation / C. Angelantonj, M. Cardella, N. Irges. - In: PHYSICS LETTERS. SECTION B. - ISSN 0370-2693. - 641:6(2006), pp. 474-480. [10.1016/j.physletb.2006.08.072]
Abstract:
The one-loop vacuum energy is explicitly computed for a class of perturbative string vacua where supersymmetry is spontaneously broken by a T-duality invariant asymmetric Scherk-Schwarz deformation. The low-lying spectrum is tachyon-free for any value of the compactification radii and thus no Hagedorn-like phase-transition takes place. Indeed, the induced effective potential is free of divergence, and has a global anti-de Sitter minimum where geometric moduli are naturally stabilised.
